Fuel pump issue?

[Paradiso]

I've had the same happen recently.  Rather than a few drops,  it was a high speed jet that covered the header pipes, which were warming rapidly.  I haven't moved that quickly in a long time.😀

The failure was around the electrical terminals, and I replaced it with a new one.  They are used on a range of different vehicles, so it's worth varying your search terms if using Ebay.  I searched 'Pierburg' and got  a NOS one for around £50.

Well , brother , it probably is coming from the electrical connectors . I do know it is leaking from mine too.  Also , get and use High pressure fuel line and use high pressure hose clamps. These type of clamps have a metal band inside of the clamp to keep from "crushing" and squeezing the rubber from out of the clamp.

 Everything you do to your bike requires perfection. In parts , labor , attention to detail . EVERYTHING . If you have ever done maintenance on aircraft , watercraft  , heavy equipment , etc. you know how important your work is .  

love your bike and give it your best !

Yeah I thought that was kinda odd, leaking at the connections.  I sometimes wonder if the non-alcohol 93 octane I had always previously used (pump gas also had Valve-Tech additive in it) may have unintended side effects similar to alcohol gas.  But since that's no longer available, I will instead be using 90 octane non-alcohol from a farm supply station nearby.

Good point "gstallions", no sense in installing a new pump using the original/now old gas lines.  Attention to detail is my rule of law (but then I still turn around to find something stupid on occasion) 

Will be sure to use the high pressure clamps, they are far superior to the standard worm drive clamps that cut into the rubber hose.  I have had very good luck with those on other fuel injection systems.

Thanks again, always appreciative.

My old 851 Ducati used to leak from 1 particular fuel pump connection after it hadn't been run for a few weeks. After a minute or 2 of starting the engine it would stop. Ride it every day, no problems with any leakage. Weird.

Well to follow up on all the troubleshooting I narrowed it down to a bad fuel pump.  Size (OD) of the Quantum fuel pump was larger than the original (Pierburg Made in USA????) so the rubber isolator boot would not work.  Had to use some turbo hose to get the attachment clamps to fit the pump mount properly.

Kiwi-Roy schematics for troubleshooting were a lot of help, as were all the other suggestions from you guys. Thanks again!!

Now the idle is running low, around 900 rpms so need to figure that out.

This bike is pissed at me for moving it to another part of the state!

Just to note, out of interest to others, I did find what is supposedly the original fuel pump, with proper insulator, but $426 was just too much. (Edit addition 5/26)  Found the same on Amazon for $154.07.  Ordered, appears same as OEM with proper boot insulator/size).  Will update upon receipt/comparison/install).
